~Becomes the first company with indigenous technology to achieve this feat globally~

 As part of the iDEX (Innovations in Defence Excellence) program under the Ministry of
Defence (MoD), QNu Labs successfully demonstrated and achieved secure communications
in-field over a distance of 325kms using a new Armos QKD variant along with the Trusted
Relay Node capability

 Accomplished world’s first implementation of secure key transfer over 150Kms between two
stations using indigenous Armos QKD technology over an installed fibre with 30db loss
India, June 08, 2022: Bengaluru headquartered QuNu Labs Pvt. Ltd. (QNu Labs), India’s first
Quantum Cryptography company, has now become the first company globally with a
commercially ready new variant of its Armos QKD system, which has broken the distance
barrier in the Quantum Key Distribution (QKD) technology. In the last week of April 2022,
QNu Labs conducted a field demonstration of its latest variant of indigenous Armos QKD
technology. This extensive field demonstration was carried over 7 days in April 2022 in
northern India, in one of the harshest terrains in the world.

QNu Labs successfully generated a pair of symmetric keys over a distance of 325 kms using
QNu’s indigenously developed 150Kms single hop, Armos QKD system and the Trusted Relay
Node technology. The most significant aspect of this innovation is that any number of
trusted nodes can now be added to the network, to extend the secure communication to
any communication node, without any distance barrier. This new Armos QKD technology
variant has been developed as part of the iDEX program under the Ministry of Defence.

Additional Secretary (DP) and CEO (DIO) Shri Sanjay Jaju, praised QNu Labs for their
continued commitment and efforts towards development of an indigenous technology in
quantum communication – specifically crediting QNu for the recent success of the world’s
first implementation of secure key transfer over 150 kms. This success attests to India’s
ability to attain the vision of an 'Atmanirbhar Bharat' and is a crucial factor towards
maintaining India’s strategic autonomy.

What makes the feat unique considering that the mentioned field demonstration used
commercially ready products by QNu on the existing optical fibre network (i.e., no special
super conducting fibre was required). This extensive and rigorous demonstration cleared all
the tests and specifications set forth – and was evaluated and witnessed by a team
consisting of an appointed Nodal Officer of Indian Army, Program Executive Defence
Innovation Organisation (DIO) Samriddh Hada and the local team of the Signals Corps.

Centric to the principle of quantum physics, Armos QKD system generates a pair of
unconditionally secure symmetric keys, enabling future proof data encryption against any
brute force attack. This milestone achieved under stringent conditions, catapults India to
the forefront of quantum secure communication technology as globally, symmetric keys
over only 100-120 kms (24db loss) have been accomplished at present in the actual field

QNu Labs new Armos QKD variant along with Trusted node technology is commercially
available on Government E-Marketplace - GeM portal, which can also be accessed through

Equipped with this technology, the Indian armed forces, intelligence agencies and national
security centric infrastructure entities can take lead against other nations in creating secure
communication networks, over long distances in real life field conditions.” said Sunil Sud,
Head Defence Business Unit, QNu Labs.

QNu labs has been a trailblazer since its inception and was recently conferred the National
Technology Award from DST in May’22 and had won the Most Innovative Product Award in
2019. QNu Labs is the only company from India to be a part of The Who’s Who of Quantum:
A list of 40+ Quantum Companies from Around the World, by The Quantum Insider.  


A leader in quantum-safe cryptography products and solutions, QNu Labs offers Quantum
Security solutions to deliver utmost data security with its patented technology. With this
indigenous technology feat, QNu Labs has established that India has tremendous potential
